TECHNICAL FIELD

This disclosure generally relates to interfaces for recommending and completing a transaction.

BACKGROUND

After a customer (e.g., seller) of a merchant (e.g., buyer) places an order, the merchant can provide information regarding the order to the user. The information provided can include basic transactional information, such as the cost and shipping destination, as well as information allowing the customer to refer back to the order if needed (e.g., transaction or order numbers). Tracking pages can also reference or provide links to information regarding the order that may be useful to the user. For example, an order for flowers can include care instructions for the flower. An order for a package to be delivered by mail can include a tracking number or a link to a tracking system for the package. However, tracking pages are often fairly static endeavors and only reference the present order made by the customer. Moreover, a merchant typically has limited options for customizing the tracking page based on the merchant’s own brand or based on the needs and interests of the customer.

DESCRIPTION OF EXAMPLE EMBODIMENTS

Particular embodiments disclosed herein may be designed to address specific problems or omissions in the current state of the art as described herein. As described herein, particular embodiments include systems and methods for automatically facilitating orders for buyers with sellers based product recommendations presented to the buyer in a tracking page for an order previously placed with the seller. In particular embodiments, a transaction processing system facilitates the placing of an order by a buyer with a seller. The transaction processing system selects one or more product recommendations for the buyer using a product recommendation model based on one or more features associated with the buyer, the seller, or the order. The transaction processing system causes an order tracking user interface corresponding to the order to be presented to the buyer on a user device of the buyer that includes a set of interactive elements. One or more of the interactive elements corresponds to a selected product recommendation. The transaction processing system receives, from the user device of the buyer, a selection of one of the one or more interactive elements corresponding to a selected product recommendation. The transaction processing system retrieves payment information for the buyer based on receiving the selection of the interactive element. The transaction processing system automatically facilitates an order for the product corresponding to the selected interactive element based on the retrieved payment information for the buyer. In particular embodiments, the transaction processing system determines a personalized presentation of the interactive elements based on the product recommendation model. The personalized presentation can include an order or position of the one or more interactive elements corresponding to the selected product recommendation in the order tracking user interface. In particular embodiments, the transaction processing system selects one or more of the product recommendations for the buyer based on, for example, a time from the placing of the order, a method of placing the order, an order history between the buyer and seller, or a user device type of the user device.

In particular embodiments, facilitating placing an order by a buyer with a seller includes the transaction processing system receiving a user identifier for the buyer, storing the user identifier in association with order information in a database associated with the transaction processing system. The order information includes one or more features used by the product recommendation model. In particular embodiments, the transaction processing system determines that the user identifier for the buyer corresponds with user account information stored in the database associated with the transaction processing system. The transaction processing system updates the user account information corresponding to the user identifier for the buyer in the database associated with the transaction processing system. In particular embodiments, the transaction processing system determines that the user identifier for the buyer does not correspond with user account information stored in the database associated with the transaction processing system. The transaction processing system creates a new record of user account information corresponding to the user identifier for the buyer in the database associated with the transaction processing system. In particular embodiments, the order tracking user interface is an email sent to the buyer on behalf of the seller, a short message service message sent to the buyer on behalf of the seller, a web page provided by merchant or provided by the transaction processing system on behalf of the seller, or a user interface of an application associated with the seller or the transaction processing system executing on the user device.

In particular embodiments, the product recommendation model is provided by the seller and the one or more product recommendations for the buyer are presented in the user interface via an application programming interface provided by the transaction processing system. In particular embodiments, the product recommendation model is configured to provide recommendations of featured products offered the seller, wherein the featured products are determined by the seller. In particular embodiments, the product recommendation model is configured to provide personalized recommendations of products offered by the seller. In particular embodiments, the product recommendation model is provided by the transaction processing system for the benefit of the seller. In particular embodiments, prior to selecting one or more product recommendations for the buyer using the product recommendation model based on one or more features associated with the buyer, the seller, or the order, the transaction processing system accesses a merchant inventory system associated with the seller, analyzes available inventory of the seller through the merchant inventory system, and normalizes the available inventory of the seller to generate training data for the product recommendation model. In particular embodiments, retrieving payment information for the buyer based on receiving the selection of the interactive element includes determining a user identifier for the buyer based on the user device and the receiving the selection of the interactive element, and retrieving the payment information for the buyer from the database associated with the transaction processing system using the determined user identifier. In particular embodiments, automatically facilitating the order for the product corresponding to the selected interactive element based on the retrieved payment information for the buyer includes placing the order for the product corresponding to the selected interactive element using the retrieved payment information for the buyer without requiring further interaction from the buyer. In particular embodiments, automatically facilitating the order for the product corresponding to the selected interactive element based on the retrieved payment information the buyer includes causing an account authentication user interface to be displayed to the user on the user device, sending a one-time password to the user device via a communication channel associated with the user identifier, receiving the one-time password from the user device via the account authorization user interface, and determining that the one-time password sent to the user device corresponds with the one-time password received from the user device via the account authorization user interface.

In further embodiments a method includes displaying, by a user device associated with a buyer, an order tracking user interface corresponding to an order previously placed by the buyer with a seller. The order tracking user interface includes interactive elements with one or more of the interactive elements corresponding to a product recommendation. The user device receives a user input corresponding to one of the one or more interactive elements corresponding to the product recommendation. The user device sends a message corresponding to the selection of the one of the one or more interactive elements to a transaction processing system. The user device receives, from the transaction processing system, a confirmation that an order has been automatically placed with the seller on behalf of the buyer for an item corresponding to the selected one of the one or more interactive elements. In particular embodiments, the user device displays an order tracking user interface corresponding to the order automatically placed with the seller on behalf of the buyer for an item corresponding to the selected one of the one or more interactive elements. In particular embodiments, subsequent to sending the message corresponding to the selection of the one of the one or more interactive elements to the transaction processing system, the user device displays an account authentication user interface and receives a user input corresponding to a one-time password via the account authentication user interface. In particular embodiments, the order tracking user interface includes an email sent to the buyer on behalf of the seller, a short message service message sent to the buyer on behalf of the seller, a web page provided by merchant or provided by the transaction processing system on behalf of the seller, or a user interface of an application associated with the seller or the transaction processing system executing on the user device.

After a customer (e.g., seller) of a merchant (e.g., buyer) places an order, the merchant can provide information regarding the order to the user. The information provided can include basic transactional information, such as the cost and shipping destination, as well as information allowing the customer to refer back to the order if needed (e.g., transaction or order numbers). Tracking pages can also reference or provide links to information regarding the order that may be useful to the user. For example an order for flowers can include care instructions for the flower. An order for a package to be delivered by mail can include a tracking number or a link to a tracking system for the package. However, tracking pages are often fairly static endeavors and only reference the present order made by the customer. Moreover, if a merchant wishes to save on costs and effort, they can use a turnkey solution for providing post-purchase support, including tracking pages. This comes, however, with a tradeoff of limited options for customizing the tracking page based on the merchant’s own brand or based on the needs and interests of the customer. Otherwise, a merchant may need to build a custom solution.

Particular embodiments described herein relate to a post-purchase support interface, referred to also herein as a post-purchase page or order tracking page, that enables novel features allowing a merchant to provide opportunities for a user to make additional purchases based on or relating to a recently placed order. In particular, through managing multiple aspects of the order placement and purchase completion process, a transaction processing system can provide a post-purchase support interface featuring one-click order placement from certain user devices. In embodiments described herein, the post-purchase support interface includes new features and behavior, including options for dynamically generated recommendations that can be customized based on merchant, the customer, and properties of a pending transaction. The one-click ordering and recommendations are based on a user account system integrated into the checkout experience that uniquely associates a user with relevant payment and other account information across merchants and throughout the post-purchase period.

Many ecommerce merchants provide merchant-specific account systems. Users can create accounts with merchants to enable features such as more convenient checkout experiences through storage and retrieval of user preferences and payment information. However, the user must affirmatively create the account, maintain a secure password, and ultimately trust the merchant to securely store their information. Currently, most ecommerce transactions are conducted with the customer operating in a “guest” mode, outside of the merchant account systems. Among independent merchants customers that conduct transactions in the guest mode cannot be tracked, their preferences cannot easily be learned, and recommendations can only be based on broad features, not personalized to the customer. Certain large merchants successfully manage user account systems, however these accounts cannot be easily shared with independent merchants.

As described herein, a transaction processing system can provide for cross-merchant user accounts, where a user can choose to associate user identifying information that uniquely identifies the user to the transaction processing system with payment information, shipping information and preferences, and an overall user profile. The transaction processing system can receive the user identifying information from a customer or a merchant during a checkout procedure for a given order. The transaction processing system can determine whether the received user identifying information corresponds to a user account and, if so, enable features of a checkout experience for the customer accordingly. For example, a customer can see their preferred payment method and shipping terms pre-populated during the checkout experience. In particular embodiments, the transaction processing system can enable a one-click checkout experience, where, after a user is logged into the transaction processing system for a checkout experience, a minimal number of interactions from the user are needed to place the order with the merchant.

In combination with these features, and using the user account system, the transaction processing system can make advanced post-purchase support interfaces available for merchants to provide to their customers. Because the transaction processing system is able to recognize a customer across merchants and even user devices, the transaction processing system can provide new features to post-purchase support interfaces, such as dynamic product recommendations presented in the post-purchase support interface. The dynamic product recommendations can be further enhanced with an easy check-out whether or not the user has recently logged into an account with the transaction processing system.

In particular embodiments, the transaction processing system can provide an application programming interface (API) for inserting product recommendations into post-purchase support interfaces. For example, the transaction processing system can determine when a user is viewing or requesting to view a post-purchase support interface for an order with a merchant. The transaction processing system can alert the merchant or a merchant vendor, that the user will be shown product recommendations through a call on the API and receive in return a set of product recommendations to display in the post-purchase support interface. In other embodiments, the transaction processing system can build a product recommendation model to identify and generate product recommendations for the user. The transaction processing system product recommendation model can be trained to identify inventory items offered by the merchant and recommend a set of the inventory items to a user in a post-purchase support interface according to criteria set by the transaction processing system, the merchant, or the user. Additionally, because the recommendations and the post-purchase support interface itself can be generated dynamically, the layout and arrangement of data on the post-purchase support interface can be adjusted according to user preferences, stated or inferred.

Ultimately, the novel post-purchase support interface and support programming interfaces provide an array of benefits to merchants, users, and the transaction processing system itself. These benefits are a result of the technologically-oriented and -rooted solutions to the technical problems, described herein, which arise in the field of facilitating e-commerce transactions, and in particular the field of post-purchase support. As an example, in addition to being features not presently available in post-purchase support technology generally, dynamically generated recommendations can ensure that computational and network resources used to render and display post-purchase support interfaces are not misused on recommendations that are irrelevant to a customer. The further integration of a so-called one-click checkout procedure for recommended items can reduce the use of computational resources to provide user interfaces to place an order using standard checkout procedures, while managing the risk of fraud or security breach associated with ecommerce purchases.

Particular embodiments disclosed herein may provide one or more of the results, effects, or benefits described herein. FIG. 1 illustrates an example method 100 for facilitating an order corresponding to a product recommendation through buyer interaction with an interactive element presented in a post-purchase serving interface. In particular embodiments, the method can begin at step 110, where a transaction processing system facilitates placing an order by a buyer with a seller. The buyer, or merchant, can be an ecommerce merchant operating a website. The buyer can use the transaction processing system in various capacities as part of their order placement and fulfillment lifecycle. For example, the transaction processing system may operate a number of APIs which allow merchants to process payments (e.g., virtual wallets, payment cards, etc.) through the transaction processing system. Certain merchants can use a more in-depth version of the services offered by the transaction processing system. For example, the merchant can use the transaction processing system to receive order information from sellers, coordinate receiving payment and shipping options form the seller, charge the sellers, track a transaction history with the seller, and, as described herein, provide for post-purchase support through the transaction processing system.

In embodiments, the buyer may select one or more items offered for sale by the seller. The buyer may add the items to a shopping cart-style interface and, when they have finished choosing items, select an interface element associated with the merchant’s storefront to initiate the checkout procedure. In particular embodiments, during the checkout procedure, the buyer can be encouraged to enter user identifying information. The user identifying information may be information to uniquely identify the user to the merchant and/or to the transaction processing system. The user identifying information can also correspond with communication channels through which the buyer can be reached on demand. As an example, user identifying information can include an email, a phone number, a handle used with particular social media platforms, etc. After receiving the user identifying information (e.g., a user identifier), the transaction processing system can request the user to enter addresses to use for shipping or billing purposes, payment information, and other, backup communication information reaches the buyer. In particular embodiments, as described, the buyer may have an account with the transaction processing system. The transaction processing system may recognize the user identifier, retrieve information to affect the order, and display the information for confirmation from the buyer rather than require the buyer to re-enter the information. Once satisfied, the buyer can select another interface element to confirm and place the order.

After the order has been placed by the buyer, the transaction processing system can ensure that the seller receives payment from the buyer and forward information necessary to fulfill the order to the seller. The transaction processing system can also store the user identifier in association with the entered order information. For example, the transaction processing system can maintain one or more databases to store user identifiers, user payment information, shipping information and preferences, and other information that is used to enable one-click checkout. The transaction processing system can also maintain, in the same or logically related databases, an order history of buyers with sellers that have been placed through the transaction processing system. The order information stored in association with the user identifier for the buyer may vary based on the information requested by the seller (and hence, the transaction processing system) during the checkout process. As described herein, this order information can be used by a product recommendation model to generate product recommendations to the buyer on request from the seller or from the transaction processing system.

In particular embodiments, after determining that the user identifier for the buyer corresponds with existing user account information stored in the database, the transaction processing system may update the user account information corresponding to the user identifier for the buyer in the database associated with the transaction processing system. Alternatively, the buyer may not have had an existing account with the transaction processing system prior to the order. The transaction processing system may determine this based on determining that the user identifier for the buyer does not correspond with user account information stored in the database associated with the transaction processing system. In response, the transaction processing system may create a new record of user account information corresponding to the user identifier for the buyer in the database associated with the transaction processing system. Note that this new account record can be created at any suitable point in the checkout process, although it may be preferred to wait until affirmative consent for creating the account has been provided by the user.

After the buyer places their order with the seller, the buyer may wish to receive or view updates associated with their order. For example, the buyer may be eagerly anticipating the delivery of the order and may want to ensure that the items in the order have shipped or track the shipping process generally. The seller may wish to provide this functionality to the buyer so that the buyer can verify that the order is proceeding. According to embodiments described herein, this post-purchase support can be provided by the transaction processing system on behalf of the seller. For example, the transaction processing system can use the contact information (e.g., user identifiers) entered by the buyer during checkout or account creation to send updates to the buyer. The updates can be delivered, for example, as short message service (SMS) messages or as emails, depending on the preferred communication channel selected by the buyer. Additionally, the transaction processing system can provide a landing page on a website operated by the seller or by the transaction processing system on behalf of the buyer. The landing page can be associated with a unique link corresponding to the order. When the transaction processing system (or merchant) receives a request for the landing page, the transaction processing system can use information encoded in the unique link to identify the order and/or the buyer and cause the relevant information to be presented to the buyer. The transaction processing system can provide for similar functionality to be presented to the user through an application executing on a user device of the user.

In response to receiving a request to generate a post-purchase support interface, e.g., an order tracking page, the transaction processing system can prepare interface elements that will be presented to the user in the post-purchase support interface. The request can be received from the merchant (e.g., requesting that an update email be sent to the buyer), from the user (e.g., requesting that that a website embodiment of the post-purchase support interface be updated), or can be provided by the transaction processing system automatically (e.g., based on an elapsed amount of time or at defined stages in the order fulfillment process). Some of the interface elements prepared by the transaction processing system can merely relay information to the buyer. For example, interface elements can relate to identifying the order or the seller. In addition, interface elements can be interactive, such as a map element showing relevant locations to the order, such as the current item location. According to the embodiments described herein, the transaction processing system can designate one or more of the interface elements to correspond to a product recommendation for the buyer.

Returning to the method 100 illustrated in FIG. 1 , in particular embodiments, at step 120 the transaction processing system selects one or more product recommendations for the buyer using a product recommendation model. The selection of the product recommendations for the buyer can be based on one or more features associated with the buyer, the seller, or the order. The features can be provided to the product recommendation model, which is configured to identify the products to be recommended to the user.

The product recommendation model can be embodied in a variety of distinct structures and can be accessed in a number of ways based on the configuration of the transaction processing system and the merchant system as well as the relationship between the two. For example, the product recommendation model can be provided by the seller. The seller may have developed their own systems for recommending products to a user, such as through an advertising system. The seller may wish to use the transaction processing system to present the recommendations, such as to use the one-click checkout features described herein but may choose to use their own product recommendation model. In said embodiments, the product recommendation model is made available for use by the transaction processing system. For example, the product recommendation model can be presented with an API that is accessible by the transaction processing system (e.g., the transaction processing system can be provided to access the model on the API). Then, when the transaction processing system is building a post-purchase support interface for display to the seller, the transaction processing system calls the API for the recommendation model and receives in return a number of product recommendations. Calls to the API can include parameters such as the number of product recommendations requested, the identity of the seller, the amount of time since the placing of the order, the items in the order, and other related features.

In particular embodiments, a relatively straightforward implementation of the recommendation may simply provide recommendations of featured products offered by the seller. For example, the seller can select certain products, based on time, location, buyer demographics, etc., to recommend to any seller on request. In particular embodiments, the product recommendation model can be configured to provide personalized recommendations. For example, based on the identity of the buyer (as captured in the user information stored by the transaction processing system), the product recommendation model can select products to recommend to the buyer that are believed or expected to be of interest to the buyer. For example, the seller can determine that, based on the buyer’s past purchases, the buyer is likely to be interested in a specific color variant of the product, or may be interested in a new product offered by the seller that the buyer has not yet purchased. The recommendations can further be informed based on the order which the buyer is reviewing.

As another example embodiment of the product recommendation model, the transaction processing system can provide the product recommendation model for use on behalf of, or for the benefit of, the merchant. In contrast to the embodiment described above, where a merchant supplies their own product recommendation model, the transaction processing system can generate its own product recommendation model as part of a full-service post-purchase support system. The product recommendation model can, for example, be a machine-learned model trained using the data available to the transaction processing system by virtue of it interfacing with users and merchants across many ecommerce fields. The data can include a corpus including the products available from merchants, a record of recommendations, a success rate based on the number of conversions, and a record of the users to whom recommendations were made, among other features. The model may be trained on only data from an individual merchant. Such a model will be highly tailored to the merchant but may lack a breadth of training experience. The model may be trained on data from merchants in a similar category or offering similar products. The model may be trained on data from across the entirety of the transaction processing system.

In particular embodiments, to train the product recommendation model the transaction processing system may analyze the inventory available from a merchant, both to collect a record to ensure recommendations are up to date (e.g., that recommendations align with available products) and to normalize the inventory for training purposes. Prior to selecting one or more product recommendations for the buyer using the product recommendation model based on one or more features associated with the buyer, the seller, or the order, the transaction processing system may access an inventory system maintained by the seller. Access to the inventory system can be provided directly from the seller or may be made available from a third party, such as when the inventory system is provided by a merchant vendor. The transaction processing system may ingest the inventory system information for use in training the product recommendation model or in making recommendations for the seller. Not all merchant inventory systems will be organized the same manner and merchant inventory systems may not provide the same set of data, differing even based on how the merchant uses the system. Therefore, some amount of normalizing the data must be performed before it can be used by the transaction processing system in making product recommendations. Normalization can include determining comparable variables and minimum amounts of data required for a product recommendation model to be viable. Normalization can also include reorganizing the data to correspond across merchants, such as by storing items according to universal identifiers (e.g., stock keeping units) instead of names attributed to the by the merchant.

In addition to personalizing product recommendations for the buyer, which will be reflected in the presentation of the post-purchase support interface, the transaction processing system can customize how the post-purchase support interface is organized. For example, the transaction processing system can modify the order of interface elements corresponding to products, icons and images associated with the product used in the interactive elements, a position of interactive elements in an absolute or relative sense, and other similar parameters.

As described herein, the transaction processing system can use a variety of data points in making recommendations. The input for recommendations for a seller can be based on the seller itself or based on the data provided by the seller to the transaction processing system. As an example only, and not by way of limitation, features that may be used to make product recommendations for a buyer include a time from the placing of the order between the buyer and seller, a history of orders between the buyer and seller, the buyer’s transactions with other merchants through the transaction processing system, the method in which the order was placed (e.g., mobile, desktop, phone, etc.), the make and model of a device used to place the order, the type and number of items included in the order, common pairings or dependencies between times (e.g., shoes and socks), colors of items in the order, materials used in manufacturing the order, and many other features.

Returning to the method 100 illustrated in FIG. 1 , in particular embodiments, at step 130 the transaction processing system causes a post-purchase support interface corresponding to the order to be presented to the buyer on a user device of the buyer. As an example, the post-purchase user interface can be a user interface to track the buyer’s order. The post-purchase user interface is specifically configured, according to the determination made by the transaction processing system discussed above, to include a number of interactive elements that provide added features to the post-purchase support interface. In particular embodiments, one or more of the interactive elements correspond to the selected product recommendations. The correspondence can be noted to the buyer based on, for example, text, images, or video used to produce the interactive elements. The correspondence can be noted by the transaction processing system based on commands associated with the interactive elements. As an example, the interactive elements can include buttons or selectable images associated with each item. The buttons can be encoded with links that cause the user device, after the buyer has selected the button, to call a programming interface of the transaction processing system with information regarding the corresponding product. In particular embodiments, multiple interactive elements can be associated with a corresponding product, with each interactive element including different associated actions. For example, a first interactive element can include a purchase action (e.g., “a Buy Now” button), while another interactive element can be used to present more information or save the product for review at a later time.

In particular embodiments, at step 140, the transaction processing system receives a selection of one of the one or more interactive elements corresponding to a selected product recommendation. For example, the interactive elements are presented in the post-purchase support interface on the user device of the buyer. The user can click or tap one of the interactive elements. The user device can then issue a call to the programming interface of the transaction processing system according to the programming associated with the interactive element. This causes a notification of the selection to be delivered to the transaction processing system.

In particular embodiments, the transaction processing system is configured to interpret the selection of an interactive element. Where the selection is configured to be interpreted as a request to purchase the product corresponding to the interactive element, at step 150, the transaction processing system retrieves payment information for the buyer. In addition, the transaction processing system may retrieve other user account information for the buyer based on receiving the selection. For example, the transaction processing system may save the buyer’s selection for use as a feature in making future recommendations. In particular embodiments, the notification of the selection can provide information to identify the buyer. For example, the link associated with the interactive element can be made unique to the buyer and can include identifying information for the buyer or a token corresponding to the identifying information. When the transaction processing system receives the selection, this identifying information and/or token can also be provided. As another example, the user device used to view and select the interactive element can send a unique device identifier for itself to the transaction processing system. The device identifier can be stored by the transaction processing system in its database of user account information as a first line of identifying a user. Through one or more of these means, the transaction processing system can identify a record corresponding to the buyer in the database associated with the transaction processing system used to store user account information. The transaction processing system can retrieve, from the record buyer order details, such as the buyer’s preferred payment method, shipping address, and preferred shipping terms.

After identifying the payment information for the buyer, at step 160, the transaction processing system may automatically facilitate an order for the product corresponding to the selected interactive element based on the retrieved payment information. The buyer may not leave the post-purchase service interface in order to complete the purchase. In certain embodiments, all that is required is for the buyer to confirm the order details with a single click. For example, a modal or other interface element configured by the transaction processing system can be presented on the user device of the buyer. The modal can include the retrieved payment information, shipping information, and other information needed to complete the transaction. In some embodiments, the selection can be interpreted as confirmation, so that no further interaction from the buyer is needed.

In particular embodiments, to ensure security of the buyer’s account, and protected against accidental one-click errors, the transaction processing system can provide an account authentication user interface. The account authentication user interface can require the buyer to enter a password to verify the buyer’s identity. In certain embodiments, the account authentication user interface requests the buyer to enter a one-time password before proceeding to log in to the buyer’s account and request the purchase of the selected product. Concurrently with displaying the account authentication user interface, the transaction processing system can send a one-time password to the user via a communication channel associated with the user identifier. For example, where the user identifier is an email, the transaction processing system can send the one-time password to the email address. Similarly, the user identifier can be a phone number and the one-time password can be sent as an SMS message. Alternatively, the approach used to send the one-time password can vary based on which user device is displaying the account authentication user interface. For example, if the transaction processing system determines that the buyer is logging in through their laptop, the one-time password can be sent to the buyer’s mobile phone (e.g., as an SMS message or push notification) to lessen the impact of a single point of failure in the security of the buyer’s devices.

After receiving the one-time password, the user can input the one-time password into the appropriate fields of the account authentication user interface, such as by typing in requested numbers. The user device then sends the one-time password to the transaction processing system. The transaction processing system can receive the one-time password from the user device and compare the received one-time password to the expected value. When the transaction processing system determines that the one-time password sent to the user device corresponds with the one-time password received from the user device via the account authorization user interface, the buyer can be allowed access to the account, including to make purchases such as the purchase for the product relating to the selected user interface.

As part of facilitating the order for the product, the transaction processing system can cause funds corresponding to the order to be moved from an account of the buyer to an account of the seller. In particular embodiments, the transaction processing system can send requests to an acquirer system, an issuer system, or another entity associated with the payment method used by the buyer to affect the transfer of funds. The transaction processing system can also send the order to the merchant for fulfillment.

FIG. 2A illustrates example interactions between systems in performing one-click transactions with product recommendations in tracking interfaces. The process begins at 231 where the user device 230 presents a checkout interface to a buyer for an order. The checkout interface can include information to allow the buyer to verify the entered information before agreeing to the purchase by selecting an appropriate user interface element. At 232, the user device 230 sends an order confirmation for the order to the transaction processing system. At 211, the transaction processing system processes the order, for example by arranging for payment between the buyer and seller and storing the order details for analytical purposes. At 212, the transaction processing system sends the order information to the merchant system 220 so that the seller can begin to fulfill the order.

At 233, the buyer requests a post-purchase support interface corresponding to the user. The user device 230 sends the request, on behalf of the buyer, to the transaction processing system 210. At 213 and 221, while preparing the post-purchase support interface, the transaction processing system 210 and merchant system 220 select one or more product recommendations using a recommendation model as described herein.

Particular embodiments disclosed herein may be implemented using one or more example architectures described herein. Underlying foundational concepts and terms of art relied upon may relate to one or more of the following:

A transaction processing system platform (of which the Bolt Platform is an example) consists of four conceptual parts. The frontend serves both the main consumer checkout flow as well as internal and external dashboards and administrative tools. The core services that power the checkout flow as well as fraud detection and payments. Bolt is architected as a set of independent services which communicate to each other via HyperText Transfer Protocol Representational State Transfer (“HTTP REST”) or AMAZON Web Services Simple Queue Service (“AWS SQS”) messages. The Bolt Application Programming Interface (“Bolt API”), which is the primary means by which merchant systems interface with Bolt, exposed to the outside world via HTTPS REST. Plugins, which are deployed to merchant systems and which connect these systems with the Bolt API.

Other foundational concepts and terms of art may relate to one or more of the following:

-   Processor integrations to automate chargeback handling (syncing,     representment) -   A regression model to predict chance of winning a representment.     From the regression model the system may derive the expected value. -   A classification model to recommend action items to the merchant.     Example action items including fighting chargebacks or not or what     is the most valuable evidence. -   Merchant integration to potentially generate evidence automatically.     Evidence may include:     -   AVS results     -   CVV results     -   Billing / shipping addresses     -   Historical orders     -   Shipment receipt     -   Tracking details     -   Third party data on the user

In all example embodiments described herein, appropriate options, features, and system components may be provided to enable collection, storing, transmission, information security measures (e.g., encryption, authentication/authorization mechanisms), anonymization, pseudonymization, isolation, and aggregation of information in compliance with applicable laws, regulations, and rules. In all example embodiments described herein, appropriate options, features, and system components may be provided to enable protection of privacy for a specific individual, including by way of example and not limitation, generating a report regarding what personal information is being or has been collected and how it is being or will be used, enabling deletion or erasure of any personal information collected, and/or enabling control over the purpose for which any personal information collected is used.

The frontend of the Bolt Platform is stored in a monorepo. It consists of the following sub-components:

-   “Connect.js” - renders the Bolt checkout button and bootstrap iframe     for checkout -   “checkout” - which is the user-facing component for checkout     experience -   “Merchant” - which is the merchant facing dashboard -   “Admin” - which is the internal dashboard used by risk analysts,     merchant success, and engineering

The core services and the APIs are stored in a monorepo. Examples of services include:

-   “API” - which is the set of APIs that power the checkout flow -   “adminapi” - which is the set of APIs that power the admin     dashboard. -   “apihooks” - which sends webhook messages to merchant’s shopping     platforms -   “AsyncJobs” - which is the job framework to handle long-running     asynchronous operations -   “Notifier” - which sends notifications such as emails and short     message service (“SMS”) messages -   “Imageproxy” - which is a lightweight proxy to serve images

Backend services may be written in go (with some machine-learning (“ML”) logic in python used for risk modeling). Frontend components may be written in React/Typescript. Data may be stored in Postgres, hosted by a relational database service (RDS). Another database used for state management may be Redis.

“Tokenizer” is a completely separate service, available in a serverless way to handle card tokenization. Tokenizer may be maintained completely separate do payment card industry security standards. Tokenizer may be made available in a serverless way, for example, through a service such as AMAZON Lambda. The tokenizer may be implemented in Typescript, powered by a postgres DB. All of the tokenizer infrastructure may be maintained by a separate provider account, with access restricted to a few people.

Integration with ecommerce platforms is supported in two ways. First, directly via the API. Second, with plugins deployed to the host instance.

Database: Data is stored in highly available postgres databases backed by AWS RDS. Databases can scale their components within available limits for disk (up to 16TB), CPU/ram/network (db.xle.32xlarge which is 64 cpu and 3,904 TB RAM).

Messaging: Both Consumer and Merchant-facing components do messaging through our Notifier Service.

Data Access: Services communicate via REST. GraphQL is used pervasively for all non-external endpoints.

Data Warehouse: A cloud data warehousing service may service as the main data warehouse that stores the refined data. AMAZON ELASTIC MAPREDUCE may be used for extract, transform, load (“ETL”) workflows and general analysis of the raw data. AWS Step functions, triggered by a cloud watch event, and AWS Lambda may be used to run the ETL workflows. Results may be loaded into the data warehouse. Code such as ETL scripts may be separately managed. Data consumers (e.g. analysts who look at checkout events) use may use plugins to run queries.

Hosting model: The systems may run on highly available containerized backend services backed, for example, by DOCKER and KUBERNETES on AWS. The backend services may be scaled up/down with zero downtime. Infrastructure for serving the frontend code is highly available and backed by AWS. Frontend serving automatically scales with traffic load.

Logging: Frontend (Bolt checkout modal) logs are sent to an error monitoring and reporting tool. All backend applications (e.g., api, paymentjobs, asyncjobs, notifier, etc.) and infrastructure logs (e.g., kubernetes, AWS) are sent to a cloud monitoring platform. Logs may be archived for long-term storage.

Monitoring: High and low level monitors exist to notify engineers of issues. Monitors are replicated to non-production environments to ensure issues can be caught before they make it to production. Monitors are managed in code to ensure consistency and to track changes. Overall application service-level agreements (SLAs) are measured, and lower level monitoring of metrics and logs may be performed using a cloud monitoring platform.
